Added new regression algorithms

* Deleted regression algorithms because they tested behavior similar to
other existing regression algorithms
* Fixed new bug in regression algorithm due to AddData changes
* Added unit tests for wrapt version and package existence

* Fix issue where data would be set to raw normalization mode
